This innovative product is the highest quality available. All you need is a 7/8" drill bit. Why pay a welder? BrewLogic's entry level Gott/ Rubbermaid fitting is anything but basic. The stainless steel bulkhead fitting provides a watertight seal and you can attach a 12" Boil Screen or 1/2" NPT barb on the inside of the kettle. This fitting comes with a brass 1/2" NPT X 1/2" Barb already attached. The attached ball valve is brass as well.
